feature is its chassis.”“It was a pleasure to be

the first one to race the R1”

The Praga R1 is a full-carbon track car designed around a composite monocoque, inspired by endurance prototypes.

Full-carbon track car

Praga R1 crash safety structure is composed of bespoke honeycomb carbon fibre monocoque, carbon/Kevlar strengthened flooring, front and rear crash boxes, and side mounted crumple zones. An independent test centre in Cranfield (UK) carried out a test of R1’s monocoque according to FIA CN standard and the monocoque survived with absolutely no damage at all. Coupled with the racing standard six point seat belt, HANS system support, helmet side support, FIA approved fuel cell, polycarbonate windows, and an integrated fire extinguisher system, you’ll never feel so safe in a race car.

The evolution of Praga’s lightweight racer.

Development of Praga’s own turbo system

in the R1T EVO allows for improved heat management,

while boosting power and saving weight.

Praga has developed their own carbon fibre intake manifold weighing only 1.7kg, compared to the 8kg of the OEM Renault Sport intake manifold. Finally the new exhaust manifold uses a v-band connection for quicker and easier replacement when needed. Additionally Praga will offer new lightweight forged rims saving 8kg of unsprung mass over the standard rims.

During testing at Praga’s home track, Slovakia ring, factory test driver, Ales Jirasak, recorded a new personal best lap time for Praga with 1:56.08 beating the old lap time of 1:58,40. Over a 2-minute lap the new Turbo sys-tem offers a 1.4 second improvement per lap.

The new R1T EVO will offer adjustable power levels, allow-ing for easier handling in tricky condition and for amateur drivers. An optimised air intake allows for more airflow to the intercooler and integrated shark fin adds stability in high speed corners. The intercooler is more efficient and more than twice the size of the previous one. This allows the system to maintain air temperatures of around 55°C even through the hottest races.“ Otherwise its missing the point. This lower air charge temperature will maintain a higher power output to the wheels and a smoother deliv-ery of torque. There is also a drop in water and oil tem-peratures. The volume that is pressurised by the turbo is now halfed and therefore builds boost quicker reducing turbo lag and improving throttle response.

Where others reach deep into their pockets to keep their engines running, the heart of your R1 will last you throughout the season. Power to

• Lightweight construction and suspension setup is optimized to enhance traction while minimising tyre and brake wear.

• Engine rebuild time of Praga R1 is 50 racing hours.

• The use of high quality parts from proven suppliers helps to reduce service costs.

Running costs

Teardrop-shaped R1 can generate downforce of up to 1,5x times its weight through its sophisticated aerodynamics. Enhanced traction and the overall capability of the car to go fast around the corners is what differentiate R1 from its competitors. The car can generate up to 3G of lateral force in corners.

The firstroad car createdby Praga since 1947We are delighted to introduce the Praga R1R. It is the first road car created by Praga since 1947 and it is here to follow up with the legendary history of Praga cars. The construction of the R1R is based on the successful race cars and is designed to provide the ultimate driving experience. Lighter than any production car, safer than competitive race cars. The R1R – Race car technology with license plates.

COMING 2018

Praga cars were always known for their versatile construction, reliability and luxury. They were driven by doctors, business men, movie stars, soldiers, presidents and even a king. The Praga brand was unique for its ability to manufacture almost anything with an engine in it. Throughout history more than 110 years long, Praga produced countlesss of types of cars, trucks, buses, tractors, trains, motorbikes, boats, airplanes, helicopters and

soon after the end of Second World War, Praga was forced to concentrate its produc-tion on buses and trucks and the company stopped all automobile production. For nearly half a century, the Praga brand was synon-ymous with V3S trucks that had legendary capabilities, both on and off the road. Emerg-ing after the fall of the Iron Curtain and the growth pains of the 1990’s, Praga focused its most of its activities on motorsport. Soon

Praga motorcycles, race trucks, trial trucks and a worldwide support system emerged to support some of the best drivers and riders in the world. It did not take long for Praga cars to come back to life as well. And where else to start than straight into the competitive world of motorsport.

Soon Praga was pro ducing ultra competitive go-karts followed by a new race car, the Praga R4S. Thanks to the success of the R4S, the Praga

R1 and R1R soon followed. Not cotent to stay grounded and to prove that there is no limit for the Praga brand, the company is now hard at work reviving their aircraft produc tion line with a new model, The Praga Alfa.

Praga joined the push for unification which also led to intro duction of the metric system throughout the coun try. By 1930’s Praga had more than 70% share of all automobile sales in Czechoslovakia and was hugely popular abroad too. Regrettably,

Although Praga presently only produces go-karts, road cars and racing cars, the company’s portfolio will soon be expanding. Praga is reviving its aircraft production line with an exciting new model – The Praga Alfa or to give it its full name, the Praga Orbis Avia SM-92T(E). The Praga Alfa is a multi-purpose, single engine, high wing, all-metal turboprop aircraft with a fixed landing gear, built to EASA CS-23 and FAA FAR 23 standards and requirements. More importantly the Praga Alfa can operate with just one pilot (if required) and carry up to 7 passengers. Power is via a Walter M601 F turboprop (or alternatively a GE H80), mounted in the nose with three-blade, all-metal tractor-type AV-803 propeller.

The aircraft has been conceptually designed to satisfy the all the requirements for easy operation and maintenance, including line servicing in different and difficult climatic conditions ranging from the Arctic Circle

Throughout it’s more than 110 year history, Praga has made quite a spectacular range of vehicles. Passenger cars, motorcycles, light trucks, buses, tractors, tanks, karts, race-cars, and even aircraft - all of them designed and developed in-house by Praga people, driven by passion for mobility.

to the sands of the Sahara. The Praga Alfa doesn’t need a paved runway for takeoff and landing, it can operate in any flat area as long as there are no obstacles and there is sufficient ground support. This aircraft can also be parked and stored in situ, without the need for a covered hanger.

A specially designed, high-quality, aerodynamic P-301 M-15 wing profile allows the aircraft to operate at a variety of different speeds. With its large control surfaces, the aircraft delivers a wide operational envelope giving the operator extended value, which is reflected in its user-friendliness and, above all, operational safety. The aircraft is equipped with large sliding side doors, which enables efficient opera tion of both cargo and passenger loading. Each customer can specify their own avionics package, from the simplest classic analogue variant all the way through advanced navigation and GPS options to a complete modern glass cockpit system.
